nullx8 Posted May 10, 2011 Share Posted May 10, 2011 Heyhoo I have the aircon in the bedroom set to 27 usally. Sometime there is water iside the casing (wich is more as normal) (the pipe is free) Set the ac to 26 or lower results in big ice-blocks in the casing Any idea how to prevent that ?

dumball Posted May 10, 2011 Share Posted May 10, 2011 lopburi3' timestamp='1305000227' post='4413447'] Unit needs service as coolant level is likely not right. From my experience of servicing cooling devices quite some years ago , external icing is caused by too much refrigerant in the system , have the pressures checked by a technician with the appropriate equipment .

soiboy1967 Posted May 10, 2011 Share Posted May 10, 2011 From my experience it is usually restricted airflow over the heat exchanger. Check the filter to see if its dirty. In our case I had to dismantle the unit and clean the cylindrical fan which was choked with dust and dirt caused limited airflow. Once cleaned the airflow was restored and the icing stopped.

transam Posted May 10, 2011 Share Posted May 10, 2011 Have it serviced, they recommend every 6 months but few do. Cost around 500bht per unit. Link to comment Share on other sites More sharing options...
Naam Posted May 10, 2011 Share Posted May 10, 2011 From my experience of servicing cooling devices quite some years ago , external icing is caused by too much refrigerant in the system , have the pressures checked by a technician with the appropriate equipment . it's the other way round. coolant is missing, unit needs to be topped up. easier to check at the outside unit (at the valves to which pressure and suction pipes are connected).
